If you dont want to modifiy your bios (thats what you need todo if you want to use any other wifi card then the whitelisted ones from lenovo) you need to use one of theese models (whitelisted from lenovo): The 6300N got 5Ghz for example.

I dont think that your idea will work, at least not with a common extender. If even the notebook only get a weak signal where the connection occasionally drops a normal repeater wich you normally plug into the socket maybe dont even find the wifi like you phone. (Usually a notebook got much bigger and better antennae as a small repeater). And even if you get a weak signal with a repeater, the connections will likley also drop like it is on your notebook, dependig on the environmental influences. I would look for repeater with external antennae like the TPLINK RE580D they should got much more power then the small extenders you just plug into the a socket. If even this is not enough, i would try to replace the sending and the reciving antenna with directional antennae (if this is possible for you).
